Need Help...How to create multi years column chart in mashzone?

Hi,

How to create multi years column chart in mashzone. I have tried a lot with no chance to succeed..

I have KPIs results (target & Actual) for 4 years, let say 2013-2016. How I can build bar chart grouped by years (each year in x axis represents two bars, Target & Actual).

Appreciate your support

Thanks
